- FIG. 4 illustrates daylight savings time protocols (for the year 2013) for common groupings of locales around the world, as well as the UTC off-set for multiple different locales of interest. For example, 2013 daylight savings time for the United States and Canada began Mar. 10, 2013 and ended Nov. 3, 2013, whereas Australia began on Oct. 6, 2013 and ends Apr. 7, 2014.
- daylight savings time protocol e.g., in the United States, Hawaii and most of Arizona do not observe daylight savings time.
- daylights savings entails a one-hour forward time shift at the start of the daylight savings time period and a one-hour backward time shift at the end of the daylight savings time period.
- the procedure by which daylight savings time is implemented can vary from region-to-region. For example, in the United States, the one-hour time shift occurs at 02:00 local time (i.e., 2:00 AM local time), whereas the European Union all shifts at 01:00 UTC (i.e., 1:00 AM UTC). Though complex, the daylight savings time protocols around the globe are well established.
- the UTC off-set information reflected by FIG. 4 is also well established, and reflects not only the difference or off-set (in hours) of each listed locale relative to UTC (e.g., wholesome Aires, Argentina has a UTC off-set of “ ⁇ 3” meaning that wholesome Aires is three hours “behind” UTC; in other words, at 05:00 (or 5:00 AM) UTC, it is 02:00 (or 2:00 AM) in wholesome Aires), but also that many of the listed locales do not follow daylight savings time. These locales are shown with bold letters in FIG. 4 .
- the UTC off-set designations reflect that the UTC off-set applicable to a particular locale differs depending upon whether or not daylight savings time is in effect (e.g., Sydney, Australia has a UTC off-set of “+10” hours when daylight savings time is not in effect, and a UTC off-set of “+11” hours when daylight savings time is in effect).
- the first display ring 70 is shown in greater detail in FIG. 5A .
- the UTC off-set indicia 110 follows the circular shape of the first display ring 70 , and includes “UTC” and sequentially arranged (relative to the “UTC” designation) negative/positive integers that represent off-sets relative to UTC (i.e., “ ⁇ 10” through “ ⁇ 1” and “+1” through “+13”).
- the city indicia 112 includes a number of different city or other locale abbreviations that are each strategically arranged relative to selected ones of the UTC off-set indicia 110 , directly implicating the UTC off-set assigned to the city/locale.
- the UTC off-set indicia 110 includes “+9” (identified at 110 a ) and the city indicia 112 includes “TYO” (identified at 112 a ).
- the TYO city indicia 112 a is aligned with the +9 UTC off-set indicia 110 a .
- “TYO” is a well understood abbreviation for the city of Tokyo, Japan.
- “TYO” is aligned with “+9”, a viewer readily understands that Tokyo has a +9 hour off-set relative to UTC (i.e., that Tokyo is 9 hours “ahead” of UTC).
- the UTC off-set indicia 110 further includes “ ⁇ 4” (identified at 110 b ) and “ ⁇ 5” (identified at 110 c ), and the city indicia 112 includes “CCS” (identified at 112 b ).
- the CCS city indicia 112 b is aligned between the ⁇ 4 and ⁇ 5 UTC off-set indicia 110 b , 110 c .
- “CCS” is a well understood abbreviation for the city of Caracas, Venezuela.
- Caracas has a ⁇ 4.5 hour off-set relative to UTC (i.e., that Caracas is 4.5 hours “behind” UTC).
- the cities or other locales represented by these and other city indicia 112 shown on the first display ring 70 are those that do not follow daylight savings time protocols and thus the UTC off-set for each city/locale will not change (as compared to cities/locales that do follow a daylight savings procedure as described above).
- the city indicia 112 can be “permanently” displayed relative to the UTC off-set indicia 110 along the first display ring 70 .
- the present disclosure is in no way limited to the city indicia 112 shown. Other cities or locales (that do not otherwise follow daylight savings time) can be included with the city indicia 112 , other abbreviation formats can be employed, etc.
- Respective ones of the apertures 114 are aligned with certain ones of the UTC off-set indicia 110 .
- a first aperture 114 a is aligned with the “ ⁇ 4” UTC off-set indicia 110 b .
- the apertures 114 are each sized and circumferentially located such that upon final assembly, a section of a respective one of the first-fifth partial city rings 88 a - 88 e ( FIG. 3 ) is visible through the corresponding aperture 114 .
- the first-fifth partial city rings 88 a - 88 e are shown in greater detail in FIG. 5B .
- the city indicia 116 a - 116 e includes a number of different city or other locale abbreviations, with the city indicia 116 a - 116 e carried by the corresponding first-fifth partial city ring 88 a - 88 e representing a grouping of geographically close (in terms of time zone) cities/locales that each follow a daylight savings time protocol.
- the city indicia 116 a of the first partial city ring 88 a includes “CAI” (identified at 116 a - 1 ), a first “PAR” 116 a - 2 , a second “PAR” 116 a - 3 , a first “LON” 116 a - 4 , a second “LON” 116 a - 5 , and “RKV” 116 a - 6 .
- the designations 116 a - 1 - 116 a - 6 are well understood abbreviations for the cities of Cairo, Paris, London, and Reykjavik, respectively, and is each sized to be displayed through a corresponding one of the apertures 114 in the first display ring 70 .
- the city indicia 116 a optionally includes redundant city/locale designations (e.g., the two “PAR” 116 a - 2 , 116 a - 3 and the two “LON” 116 a - 4 , 116 a - 5 ) for reasons made clear below.
- the cities implicated by the city indicia 116 b - 116 e of the remaining partial city rings 88 b - 88 e can follow a similar format (i.e., common grouping of cities/locales following daylight savings time and geographically proximate one another at least in terms of time zone), with some abbreviations being repeated for reasons made clear below.
- the partial city rings 88 a - 88 e underlie the first display ring 70 , arranged such that selected ones of the city indicia 116 a - 116 e are visible through a corresponding one of the apertures 114 .
- the particular city indicia 116 a - 116 e visible through one or more or all of the apertures 114 will change. For example, FIG.
- FIG. 6A illustrates one possible arrangement of the first display ring 70 relative to the partial city rings 88 a - 88 e (it being understood that the partial city rings 88 a - 88 e are primarily hidden behind the first display ring 70 in the view of FIG. 6A and are thus referenced generally).
- the partial city rings 88 a - 88 e are arranged relative to the first display ring 70 such that a selected one of the city indicia 116 a - 116 e is visible through respective ones of the apertures 114 , and the so-displayed city indicia is aligned with a corresponding one of the UTC off-set indicia 110 .
- the first partial city ring 88 a is arranged relative to the first display ring 70 such that the second “PAR” city indicia 116 a - 3 is visible through a second aperture 114 b otherwise aligned with a “+1” UTC off-set indicia 110 d .
- the third partial city ring 88 c is arranged relative to the first display ring 70 such that a first “CHI” city indicia 116 c - 4 (also identified in FIG.
- FIG. 6B illustrates a second possible arrangement of the first display ring 70 relative to the partial city rings 88 a - 88 e (that again are primarily hidden in the view of FIG. 6B ).
- the third and fifth partial city rings 88 c , 88 e have moved or rotated (about the central axis C) relative to the first display ring 70
- a relationship between the first, second and fourth partial city rings 88 a , 88 b , 88 d relative to the first display ring 70 has not changed.
- the change in relationship between the third and fifth partial city rings 88 c , 88 e relative to the first display ring 70 can be accomplished by moving the first display ring 70 and/or moving the third and fifth partial city rings 88 c , 88 e relative to one another.
- the third partial city ring 88 c is arranged relative to the first display ring 70 such that a second “CHI” city indicia 116 c - 5 (also identified in FIG. 5B ) is visible through a fourth aperture 114 d otherwise aligned with a “ ⁇ 6” UTC off-set indicia 110 e .
- the second display ring 72 is concentrically disposed between the primary display 28 and the first display ring 70 , with the second display ring 72 being rotatable relative to the primary display 28 and the first display ring 70 .
- the second display ring 72 carries or displays hour indicia 120 , consisting of numbers or letters that collectively represent a twenty-four hour day in sequential order.
- the hour indicia 120 includes differentiators between midnight and noon (e.g., “MDNT” hour indicia 120 a and “NOON” hour indicia 120 b ), with consecutive numbers 1 - 11 between the MDNT and NOON representing the hours between midnight and noon (e.g., the hour indicia 120 includes the number “1” (identified at 120 c ) immediately adjacent (in the clockwise direction) the “MDNT” hour indicia 120 a and is thus readily understood to represent 1:00 AM; a second number “1” (identified at 120 d ) is displayed immediately adjacent (in the clockwise direction) the “NOON” hour indicia 120 b and is thus readily understood to represent 1:00 PM).
- the direction of rotation may change and require the adjacent numbers to be incremented in the counter-clockwise direction.
- the hour indicia 120 can also assume a variety of other forms.
- the second display ring 72 allows a viewer of the watch assembly 46 to more quickly determine the current time in various locales around the globe without changing the current selected city or the primary display 28 time.
- the hour and minute hands 22 , 24 are arranged relative to the primary display 28 to indicate a current time of 10:00; the AM/PM indicia 106 visible at the primary display 28 is “P”, thus confirming that the current time is 10:00 PM.
- the hour indicia 120 of the second display ring 72 is generally aligned with locales displayed at or through the first display ring 70 , thus informing a viewer as to the corresponding current time in the displayed locales.
- the “NOON” hour indicia 120 b is generally aligned with the “TYO” city indicia 112 a , readily informing a viewer that the current time in Tokyo is 12:00 noon.
- a viewer could alternatively calculate the current time in Tokyo by noting the “ ⁇ 5” UTC off-set indicia 110 c associated with the city to which the watch has been set as mentioned above (Chicago), and the “+9” UTC off-set indicia 110 a associated with Tokyo. Comparing these two UTC off-set values, a viewer is readily informed that Tokyo is 14 hours ahead of the locale to which the watch has been set; thus, adding 14 hours to the displayed current time of 10:00 PM results in 12:00 noon in Tokyo.
- the second display ring 72 allows the viewer to more quickly ascertain this same information.
- the “1” (AM) hour indicia 120 c is generally aligned with the “RIO” city indicia 116 b - 2 (also identified in FIG. 5B ) that is otherwise visible through a fifth aperture 114 e , readily informing a viewer that the current time in Rio de Janeiro is 1:00 AM.

- controller 146 FIG. 8
- Several of the optional operational programs automatically effectuated by the controller 146 in some embodiments are provided below, it being understood that the present disclosure is not limited to any one or more or all such operations.
- the watch 20 has been set to display a current time of 1:00 PM, a current date of Jun. 11, 2013, and a current locale of Tokyo (or any other locale that is in the same time zone as Tokyo).
- the current time i.e., arrangement of the hour and minute hands 22 , 24
- the current date are “entered” by a user via actuation of the time and/or date set posts 136 , 138 .
- the current locale is “entered” by a user via rotation of the first display ring 70 until the locale of interest is aligned with the twelve o'clock position.
- the bezel 180 can be lifted by the user so as to engage the first display ring 70 and then rotated to bring the desired locale to the twelve o'clock position.
- the watch 20 can include an optional selection indicator 200 that highlights to a user which city/locale has been selected as the current locale.
- the optional selection indicator 200 where provided, can be located at various positions, such as the twelve o'clock position as shown, the six o'clock position, etc. Regardless, information relating to the set current time, current date and current locale is identified and acted upon by the controller 146 ( FIG. 8 ), with the controller 146 in turn operating to arrange the second display ring 72 and the partial city rings 88 a - 88 e in an appropriate fashion.
- the second display ring 72 has been rotated to align the “1” (PM) hour indicia 120 d (hidden behind the minute hand 24 in FIG. 11A ) with the 12 o'clock position.
- the controller 146 is programmed with daylight savings time protocols throughout the world, and locates the partial city rings 88 a - 88 e relative to the first display ring 70 based upon reference to the set current date so that correct information is displayed by the watch 20 .
- daylight savings time is in effect for some of the cities/locales and is not in effect in others.
- daylight savings time is in effect in Chicago and as such, Chicago is five hours “behind” UTC; the controller 146 has thus prompted movement of the third partial city ring 88 c relative to the first display ring 70 such that the first “CHI” city indicia 116 c - 4 is aligned with and visible through the third aperture 114 c associated with the “ ⁇ 5” UTC off-set indicia 110 c .
- an “11” (PM) hour indicia 120 e of the second display ring 72 is aligned with the visible “CHI” city indicia 116 c - 4 , informing the viewer that it is currently 11:00 PM in Chicago.
- daylight savings time is not in effect in Sydney on Jun.
- the watch 20 operates in a conventional manner, with the hands 22 - 26 and the AM/PM ring 86 moving to accurately display the current time of the selected city; the displayed current date information similarly changes in a conventional manner, with the day ring 84 , the month ring 82 and the year rings 80 a - 80 d being prompted to automatically, either by standard watch mechanisms or as dictated by the controller 146 .
- the controller 146 tracks the current date and is programmed to alter some or all of the partial city rings 88 a - 88 e relative to the first display ring 70 (and/or vice-versa) when the current date implicates a change in daylight savings time in one or more locales associated with the partial city rings 88 a - 88 e .
- FIG. 11B is a view of the watch 20 of FIG. 11A displaying a current time of 1:00 PM but at a later date in time.
- the user has not “entered” any new settings into the watch 20 between the views of FIGS. 11A and 11B (e.g., the current locale setting of Tokyo has not changed); instead, the displayed current date has progressed to Dec. 11, 2013.
- FIG. 11B (Dec. 11, 2013) with FIG. 11A (Jun. 11, 2013)
- the difference in dates (Jun. 11, 2013 of FIG. 11A vs. Dec. 11, 2013 of FIG. 11B ) does not cause the controller 146 to move or rotate the first display ring 70 or the second display ring 72 .
- the controller 146 has automatically prompted the partial city rings 88 a - 88 e to move pursuant to a programmed protocol. For example, on Dec.
- Sydney is now 11 hours “ahead” of UTC; the controller 146 has thus prompted movement of the fifth partial city ring 88 e relative to the first display ring 70 such that the “SYD” city indicia 116 e - 2 is aligned with and visible through the aperture 114 g associated with the “+11” UTC off-set indicia 110 g (and with a “3” (PM) hour indicia 120 h of the second display ring 72 ).
- the user is correctly informed that it is currently 3:00 PM in Sydney.
- FIG. 11B illustrates the watch 20 of FIG. 11B , immediately after the first display ring 70 has been rotated by a user (e.g., via the bezel 180 ) to bring the “MOW” city indicia 112 c within the selection indicator 200 (i.e., the first display ring 70 has been rotated to locate the “MOW” city indicia 112 c at the twelve o'clock position).
- “MOW” is readily understood to be an abbreviation for the city of Moscow, Russia. This hypothetical scenario might occur, for example, were the user to have traveled from Tokyo to Moscow on Dec. 11, 2013, and upon arriving, simply rotated the first display ring 70 to locate “MOW” in the selection indicator 200 . This rotation may or may not require lifting the bezel 180 and holding the bezel 180 in the lifted position during rotation. Alternatively, this rotation could be accomplished by rotation of an additional crown intended for that purpose. Once the new locale has been “entered” by the user, the controller 146 automatically recognizes the change the time zone setting. Comparing FIG. 12 to FIG.
- the controller 146 has automatically prompted the hour hand 22 to rotate to a position indicative of 8:00, and the AM/PM ring 86 to display “A” at the primary display 28 .
- the display of the watch 20 has been automatically changed to correctly indicate that the current time (in the Moscow time zone) is 8:00 AM (and as a point of confirmation, in the view of FIG. 11B (i.e., just prior to user-initiated movement of the first display ring 70 ), an “8” (AM) hour indicia 120 i provided with the second display ring 72 is aligned with the “MOW” city indicia 112 c ).
- the controller 146 has also automatically prompted the second display ring 72 to rotate in a corresponding fashion, aligning the “8” (AM) hour indicia 120 i with the “MOW” city indicia 112 c at the twelve o'clock position.
- the controller 150 has prompted the partial city rings 88 a - 88 e to move in accordance with the sensed movement of the first display ring 70 , maintaining the same city indicia-to-aperture 114 /UTC off-set indicia 110 relationships (e.g., the designation in FIG. 11B that Chicago has a UTC off-set of “ ⁇ 6” is duplicated in FIG. 12 ).
- all of the partial city rings 88 a - 88 e can be coupled mechanically to the first display ring 70 such that they all move in concert when the user moves “MOW” to the selected city position.
- the “new” current locale being entered or set to the watch 20 was carried or permanently displayed on the first display ring 70 .
- the controller is programmed to perform similar, automated operations under circumstances where new current locale being entered by the user is provided on one of the partial city rings 88 a - 88 e that underlie the first display ring 70 .
- the controller can be programmed to effectuate a change in the displayed date under circumstances where the entered change in locale implicates a change in date.
- the watch 20 as set as in FIG. 11A displays a current time of 1:00 PM in Tokyo (or other locale in the same time zone as Tokyo) on Jun. 11, 2013.
- FIG. 13 illustrates the watch 20 of FIG.
- the first display ring 70 has been rotated to bring the “CHI” city indicia 116 c - 4 (otherwise carried by the third partial city ring 88 c ) within the selection indicator 200 .
- the partial city rings 88 a - 88 e can be linked to the first display ring 70 such that when the first display ring 70 is lifted and rotated, the partial city rings 88 a - 88 e move in tandem with the first display ring 70 and the bezel 180 .
- the controller 146 can be programmed to automatically prompt movement of the partial city rings 88 a - 88 e in tandem with the first display ring 70 .
- the “CHI” city indicia 116 c - 4 is entered as the current locale in the arrangement of FIG. 13 .
- Chicago is fourteen hours “behind” Tokyo; thus 1:00 PM on Jun. 11, 2013 in Tokyo corresponds with 11:00 PM on Jun. 10, 2013 in Chicago.
- the controller is programmed with this information, and upon recognizing that Chicago has been entered as the set locale, automatically prompts movement of the hour hand 22 to indicate 11:00, movement of the AM/PM ring 86 to display “P”, and movement of the date ring 84 to display “10”.
- FIG. 14A shows the watch 20 displaying a current time of 1:59:59 AM (i.e., the hour hand 22 is approximately aligned with the 2 o'clock position of the primary display 28 ) on Mar. 10, 2013 for the set or selected city of Chicago.
- the third partial city ring 88 c is arranged relative to the first display ring 70 such that the second “CHI” city indicia 116 c - 5 is aligned with, and visible through, the aperture 114 d that is otherwise aligned with the “ ⁇ 6” UTC off-set indicia 110 e .
- the second “CHI” city indicia 116 c - 5 is aligned with, and visible through, the aperture 114 d that is otherwise aligned with the “ ⁇ 6” UTC off-set indicia 110 e .

- the “3” (AM) hour indicia 120 k is correctly aligned with the displayed “CHI” city indicia 116 c - 4 .
- the watch 20 is programmed to correctly account for the fact that while a one hour forward time shift has been effectuated in Chicago (at 2:00 AM on Mar. 10, 2013), most other locales around the world do not experience that same one hour forward time shift at the same time.
- the partial city rings 88 a , 88 b , 88 d , 88 e i.e., the partial city rings apart from the third partial city ring 88 c that otherwise carries the “CHI” city indicia

- Each of the month, year and AM/PM rings 314 - 318 rotate about a corresponding center point that is off-set from a center point of the first and second display rings 70 , 72 .
- the month ring 314 is configured such that upon final assembly, individual months (or abbreviations indicative of each month of the year) are selectively displayed through the corresponding aperture 306 in the primary display 302 . Similar relationships are established by the year and AM/PM rings 316 , 318 relative to the apertures 308 , 310 .
- FIGS. 17A and 17B Another embodiment of a world watch 400 in accordance with principles of the present disclosure is shown in FIGS. 17A and 17B (with the view of FIG. 17B illustrating the watch 400 with various front face display components removed).
- the watch 400 is akin to the watch 20 described above, and generally includes a controller apparatus (not shown) configured (e.g., programmed) to automatically effectuate changes in information displayed at a face of the watch 400 in response to various events (e.g., a daylights saving time event, user-prompted change in set time, date or selected time zone city).
- the watch 400 includes the hour, minute and second hands 22 - 26 and the bezel 180 as described above.
- the watch 400 includes a primary display 402 and a display ring 404 .
- the primary display 402 may or may not include or display hour indicia, with the hands 22 - 26 moving relative to the primary display 402 to convey current time information (e.g., in the view of FIG. 17A , the hands 22 , 24 are indicating a current time of approximately 10:10).
- the primary display 402 forms several openings or apertures through which indicia on components located below the primary display 402 are selectively visible. For example, and as described in greater detail below, the primary display 402 forms a year aperture 406 , a month aperture 408 , an upper date and AM/PM aperture 410 , and a lower date and AM/PM aperture 412 .
- the display ring 404 is akin to the first display ring 70 described above, and is connected to the bezel 180 so as to be rotatable about the primary display 402 .
- the display ring 404 includes or displays city indicia 414 (referenced generally).
- the cities implicated by the city indicia 414 of the display ring 404 represent locales that do not follow or observe daylight savings time.
- the display ring 404 further defines city apertures 416 a - 416 c for reasons made clear below.
- FIG. 17B provides a view of the watch 400 with the primary display 402 and the display ring 404 removed, although an outlined representation of the various apertures 406 - 412 and 416 a - 416 c is provided.
- FIG. 17B reveals that the watch 400 further includes partial city rings 420 a - 420 c , year rings 422 (collectively identified), a month ring 424 , upper date rings 426 (collectively identified), an upper AM/PM ring 428 , lower date rings 430 (collectively identified) and a lower AM/PM ring 432 .
- the first-third partial city rings 420 a - 420 c are circumferentially aligned with a respective one of the first-third city apertures 416 a - 416 c .
- various ones of the city indicia 434 carried on or displayed by the partial city rings 420 a - 420 c are selectively visible through a corresponding one of the city apertures 416 a - 416 c depending upon a rotational position of the particular city ring 420 a - 420 c relative to the display ring 404 (and thus relative to the city apertures 416 a - 416 c ).
- the partial city rings 420 a - 420 c are linked (directly or indirectly, mechanically or electromechanically) to a user actuator, for example the bezel 180 , so that a user can effectuate a change in a rotational position of one or all of the partial city rings 420 a - 420 c relative to the display ring 404 (and thus a change in the displayed city indicia 434 relative to the corresponding city aperture 416 a - 416 c ).
- the partial city rings 420 a - 420 c can be linked (directly or indirectly, mechanically or electromechanically) to a controller (not shown) provided with the watch 400 and pre-programmed as described above; the controller can selectively effectuate changes in the rotational position of one or more of the partial city rings 420 a - 420 c relative to the display ring 404 (and thus relative to the corresponding city aperture 416 a - 416 c ) in response to various user inputs and/or daylight savings time events across the globe.
- the controller is programmed to “recognize”, at least in part, a designated city as having been “selected” by a user, and to base various daylight savings time operations off of the selected city.
- a user can designate or select a desired city by manipulating the display ring 404 and/or the partial city rings 420 a - 420 c to align the particular city indicia 414 or 434 at the twelve o'clock position. As evidenced by the view of FIG.
- a relationship of the city indicia 414 (of the display ring 404 ) relative to the city apertures 416 a - 416 c (and thus relative to the city indicia 434 of the partial city rings 420 - 420 c ) is such that in many instances, two cities can be aligned at the twelve o'clock position (i.e., one of the city indicia 414 of the display ring 404 and one of the city indicia 434 of partial city rings 420 a - 420 c ).
- the city indicia 434 of the first partial city ring 420 a of “CHICAGO” is aligned with the twelve o'clock position, as is the city indicia 414 of the display ring 404 of “BANGKOK”. Relative to the twelve o'clock position, then, the aligned cities can be referred to as an upper designated city 440 and a lower designated city 442 . With the arrangement of FIG. 17A , the upper designated city 440 is “CHICAGO”, and the lower designated city 442 is “BANGKOK”.
- the upper designated city 440 can be provided by the city indicia 414 of the display ring 404 , and the lower designated city 442 provided by the city indicia 434 of one of the partial city rings 420 a - 420 c.
- the upper and lower designated cities 440 , 442 represent two cities that are currently twelve hours out of phase with one another.
- the user is not required to “select” or input both of the upper and lower designated cities 440 , 442 ; instead, the user merely manipulates the watch 400 such that the city corresponding (from a time zone perspective) to the user's current locale (or the city the user otherwise desires to “select”) is at the twelve o'clock position.
- the watch 400 will self-prompt the corresponding, twelve hours out-of-phase companion city to also be aligned with the twelve o'clock position. For example, with the arrangement of FIG.
- the user may have intended to select “CHICAGO” and thus manipulated the watch 400 such that “CHICAGO” was aligned with the twelve o'clock position (and thus serving as the upper designated city 440 ).
- the watch controller determines the corresponding, twelve hour out-of-phase city and prompts alignment of the so-determined city with the twelve o'clock position. For example, with the arrangement of FIG. 17A , on Apr.
- the watch 400 can include other features that further highlight a “selected” city to a user as with previous embodiments. Further, the controller can be programmed such that certain user inputs or actuations serve to designate that a particular city has been selected. Regardless, the watch 400 can display information that allows a viewer to quickly discern time and/or date differences between the upper and lower designated cities 440 , 442 .
- the year rings 422 are aligned with the year aperture 406 and are operated as with previous embodiments.
- the month ring 424 is aligned with the month aperture 408 and is operated as with previous embodiments.
- the upper date rings 426 and the upper AM/PM ring 428 are aligned with the upper date and AM/PM aperture 410 .
- the upper date rings 426 and the upper AM/PM ring 428 are operated as described above, and provide date and AM/PM information for the upper designated city 440 .
- the upper date and AM/PM rings 426 , 428 indicate that the current time and date in the upper designated city 440 of “CHICAGO” are 10:10 PM on Apr. 23, 2014.
- the lower date rings 430 and the lower AM/PM ring 432 are aligned with the lower date and AM/PM aperture 412 .
- the lower date rings 430 and the secondary AM/PM ring 432 are operated as described above, and provide date and AM/PM information for the lower designated city 442 .
- the lower date and AM/PM rings 430 , 432 indicate that the current time and date in the lower designated city 442 of Bangkok are 10:10 AM on Apr. 24, 2014.
- the controller is programmed to control operation of the various rings 422 - 432 in accordance with preprogrammed information or algorithms.
- the watch 400 could be arranged such that a city or locale following a non-integer time zone off-set (relative to UTC) is aligned with the twelve o'clock position (e.g., Caracas, Tehran, etc.). Under these circumstances, the so-selected city will serve as the lower designated city 442 . No counterpart, twelve hour out-of-phase companion city is available, such that only one city will be aligned with the twelve o'clock position. The information displayed at the lower date and AM/PM aperture 414 will correspond with the lower designated city 442 .
- the watch controller can either prompt the upper date and AM/PM rings 426 , 428 to a “partially displayed” position (e.g., a date and/or AM/PM designation is only partially visible through the upper date and AM/PM aperture 410 ) or to a blank position in which no information is displayed at the upper date and AM/PM aperture 410 .
- the watch 400 can be configured to show or display indicia indicative of all thirty-seven time zones as described elsewhere in the present disclosure.
- the year rings 422 can be omitted.

- the mechanical automated daylight savings time automated self-correction features of the watch 500 are premised upon the recognition that every year, each region of the world programmatically begins and ends daylight savings time at the same time of day on the same Sunday of the same month.
- a mechanical movement can be incorporated into the watch 500 that counts the number of Sundays in each month, in each time zone, and at the correct Sunday at the correct time of year, triggers the one hour movement of the displayed cities within their respective daylight savings time zone.
- FIG. 19 is a chart illustrating the nine distinct states.
- the watch 500 optionally includes a mechanical accounting of: day of week, month, date, counting of Sundays, AM vs. PM, and exact time of day, across the world for the displayed cities (e.g., forty-two cities), representing each of the world's thirty-seven time zones, clustered into the five distinct world region daylight savings time schedules.

Abstract
A world watch capable of automatically adjusting displayed information otherwise indicating time of day around the world upon occurrence of a daylight savings time event.
Description
- This Non-Provisional Patent Application claims the benefit of the filing date of U.S. Provisional Patent Application Ser. No. 62/062,205, filed Oct. 10, 2014, entitled “World Watch,” which is herein incorporated by reference.
- The present disclosure relates to watches (e.g., wristwatches) providing world-wide time information. More particularly, it relates to analog-type display watches providing a user with the ability to quickly determine the current time in any time zone in the world.
- Frequent business travelers that visit various geographies struggle with the constant need to reset their watch or to use various time telling websites or apps to quickly check the current local time of various other locations. While attempts have been made to develop an analog-type watch (i.e., a circular, twelve hour clock display with hour and minute hands) that displays information indicative of the current time in multiple other locales, an easy-to-use and easily understood construction has not been achieved. The difficulties in devising a satisfactory watch design are not surprising given the complexities of time zone designations across the globe. As a point of reference, there are twenty-four official time zones in the world, each divided into units of one hour relative to the coordinated universal time (UTC). Additional, unofficial time zones that have been implemented in various locales set at a non-integer multiple of one hour (e.g., set an increment of a half-hour or quarter-hour relative to the UTC), bringing the total number of time zones to thirty-seven. These differences are desirably accounted for by the watch's display. Making the time difference calculation and display from one time zone to another even more difficult is the concept of daylight savings time. Different locales across the globe institute daylight savings at different times of the year (and yet other locales do not practice daylight savings). It is exceedingly difficult for an analog-type watch display to account for daylight savings time differences in multiple locales without requiring complicated mental calculations or manual intervention by the user.
- For example, current multi-time zone watches exist that represent different time zones as multiple individual dials without indication of the location to which the display time is correlated to. Additionally, these watches required the user to manually set the time for each display, including making shifts for daylight savings time.
- Other watches have taken the approach of providing a distinct interface displaying the name or abbreviation of the locale whose time is being displayed. The user sets the primary time zone by rotating a bezel in a setup mode of the watch to the correct city by aligning the city with a designated position and then inputting the current time. The user is then able to adjust the bezel to an alternate city, which causes a secondary hour hand on the watch to adjust to the current local time (hour) of the selected city. Even with watches of this type (preprogrammed time zone offsets), however, the user is still required to manually adjust the primary display for daylight savings time or at the very least manually activate a daylight savings time mode of operation.
- In light of the above, a need exists for a world watch that displays current time information for multiple locales in an easy-to-understand format and that automatically accounts for daylight savings conventions in each region of interest.

The world watches of the present disclosure can incorporate various display formats and/or mechanisms. By way of two non-limiting examples, one embodiment of a
world watch 20 in accordance with principles of the present disclosure is shown inFIG. 1A , and a second embodiment world watch 20′ is shown inFIG. 1B . Thewatches watch 20 formatted to display information indicative of twenty-four time zones and thewatch 20′ formatted to display information indicative of all thirty-seven time zones. These, and other time zone display formats can be incorporated into any of the watches of the present disclosure. - With specific reference to
FIG. 1A , thewatch 20 is generally configured to be highly portable, carried by a user in a conventional manner (e.g., wristwatch, pocket watch, etc.), and has an analog-type watch display including anhour hand 22, aminute hand 24, and asecond hand 26. The hands 22-26 rotate about a common central axis C of thewatch 20, as do several other components as described below. The hour andminute hands primary display 28, and in particular relative toconventional hour indicia 30 carried by theprimary display 28. As a point of reference, in the view ofFIG. 1A , the hour andminute hands 24 are arranged to indicate a current time of approximately 10:10. In addition, and as described in greater detail below, thewatch 20 provides current date information and displays information indicative of the correct current time in a plethora of other locales (e.g., worldwide cites), adjusted for the differences in daylight savings time protocols (if any) implemented by the selected current locale of the user and the other locale(s) of interest as of the current date, in a manner that can quickly be determined by a user. As a point of reference, thewatch 20 can include a locale or city selection indicator (described below) or the selected locale or city is optionally arranged at the twelve o'clock position by the user in the absence of a city selection indicator. Thus, selected city in the view ofFIG. 1A is “CHI” (Chicago). While thewatch 20 has a conventional analog-type display and incorporates various mechanical mechanisms (e.g., gears) for effectuating movement of various components, a digital controller is also included, programmed to control operation of the mechanisms in a predetermined fashion. - In some embodiments, and as shown in
FIG. 2 , thewatch 20 includes acase 40, aback cover 42, a front cover orglass 44 and awatch system 46. Thecase 40 is generally configured to receive and maintain thewatch system 46, and can have a wide variety of shapes and sizes. In some embodiments, thecase 40 is ring-shaped, forming various surface features configured to mate with corresponding features of thewatch system 46 upon final construction. Theback cover 42 is configured for assembly to thecase 40, serving to protect thewatch system 46. In some embodiments, theback cover 42 is removably coupled to thecase 40 to facilitate user access to one or more components of the watch system 46 (e.g., a battery). One or both of thecase 40 and theback cover 42 optionally includes one or more features that facilitate connection to one or more other components commonly associated with hand-held watches (e.g., aclasp 48 or similar structure for connection to a wristband). Thefront cover 44 is similarly configured for assembly to an opposite side of thecase 40 and can be transparent or substantially transparent (e.g., glass) to facilitate user viewing of thewatch system 46. It will be understood that thecase 40, theback cover 42 and thefront cover 44 can assume a wide variety of other forms that may or may not be directly implicated by the drawings. - In addition to the hands 22-26 and the
hour indicia 30, thewatch system 46 includes other display components intended to display information to a user, as well as mechanisms for controlling a relationship of the components relative to one another. For example,FIG. 3 illustrates thewatch system 46 as including afront display assembly 50, arear display assembly 52, acontrol assembly 54 and abezel assembly 56. Details on the various components are provided below. In general terms, thefront display assembly 50 displays various time and date related information to a user, with the so-displayed information being augmented by information provided by components of therear display assembly 52 that otherwise underlies thefront display assembly 50. Thecontrol assembly 54 dictates locations of various components of the front andrear display assemblies bezel assembly 56 maintains the front andrear display assemblies - For ease of explanation, it is useful to first identify major components of the front and
rear display assemblies front display assembly 50 includes, in some embodiments, the hands 22-26, theprimary display 28, afirst display ring 70, and asecond display ring 72. Therear display assembly 52 includes optional first-fourth year rings 80 a-80 d, amonth ring 82, aday ring 84, an AM/PM ring 86, and first-fifth partial city rings 88 a-88 e. In general terms, the year rings 80 a-80 d (where provided), themonth ring 82, theday ring 84, and the AM/PM ring 86 correlate with theprimary display 28, whereas the first-fifth partial city rings 88 a-88 e correlate with thefirst display ring 70. - As mentioned above, the
primary display 28 can be akin to a conventional twelve hour clock face, and carries thehour indicia 30. The hour indicia 30 in some embodiments are arranged about a circular shape of theprimary display 28 in a conventional twelve hour clock face fashion, but can also be arranged in a 24 hour clock face fashion, and can include one or more numbers typically associated with a clock (e.g., relative to the circular shape of theprimary display 28, the hour indicia includes a “2” located at the two o'clock position, a “4” located at the four o'clock position, etc.). In addition, theprimary display 28 forms or defines one or more apertures through a thickness thereof and through which date and other information carried by therear display assembly 52 is visible. For example, theprimary display 28 can form anoptional year aperture 90, amonth aperture 92, and aday aperture 94. The year aperture 90 (where provided) is sized and circumferentially located such that upon final assembly, sections of each of the first-fourth year rings 80 a-80 d are visible through theyear aperture 90. In this regard, each of the year rings 80 a-80 d can carry number indicia 100 (referenced generally for thefirst year ring 80 a), such as the numbers “0”-“9”. The indicia 100 on each of the year rings 80 a-80 d is equidistantly spaced and arranged such that upon rotation of the year rings 80 a-80 d relative to theprimary display 28, individual ones of the number indicia 100 carried by each of the year rings 80 a-80 d can be aligned with and visible through the year aperture 90 (e.g., in the view ofFIG. 1A , the year rings 80 a-80 d are arranged relative to theyear aperture 90 such that the number “2013” is collectively displayed and readily understood by a user as indicating the year 2013). In other embodiments, the year rings 80 a-80 d, and thus theyear aperture 90, can be omitted. - The
month aperture 92 is aligned with theyear aperture 90, and is sized and circumferentially located such that upon final assembly, a section of themonth ring 82 is visible through themonth aperture 92. In this regard, themonth ring 82 carries month indicia 102 (referenced generally) representative of each month of the year. The month indicia 102 can be abbreviations commonly understood for each month, or can take other forms that a user would understand to implicate a particular month of the year. Regardless, themonth ring 82 is arranged relative to theprimary display 28 such that with rotation of themonth ring 82 relative to theprimary display 28, individual ones of the month indicia 102 are aligned with and visible through the month aperture 92 (e.g., in the view ofFIG. 1A , themonth ring 82 is arranged relative to themonth aperture 92 such that the month indicia “JUN” is displayed and readily understood by a user as indicating the month of June). - The
day aperture 94 is aligned with themonth aperture 92, and is sized and circumferentially located such that upon final assembly, a section of theday ring 84 is visible through theday aperture 94. In some embodiments, theday aperture 94 is further sized and arranged such that a section of the AM/PM ring 86 is also visible through theday aperture 94. In other embodiment, a separate aperture can be provided for the AM/PM ring 86. Theday ring 84 carries day indicia 104 (referenced generally) typically in numeric form (e.g., the numbers “1”-“31”). Theday ring 84 is arranged relative to theprimary display 28 such that with rotation of theday ring 84 relative to theprimary display 28, individual ones of theday indicia 104 are aligned with and visible through the day aperture 94 (e.g., in the view ofFIG. 1A , theday ring 84 is arranged relative to theday aperture 94 such that the day indicia “11” is displayed and readily understood by a user as indicating the eleventh day of the month). The AM/PM ring 86 carries AM/PM indicia 106 (referenced generally) representative of AM or PM (e.g., the letters “A” and “P”). The AM/PM ring 86 is arranged relative to theprimary display 28 such that with rotation of the AM/PM ring 86 relative to theprimary display 28, individual ones of the AM/PM indicia 106 are aligned with and visible through the day aperture 94 (e.g., in the view ofFIG. 1A , the AM/PM ring 86 is arranged relative to theday aperture 94 such that the AM/PM indicia “P” is displayed and readily understood by a user as indicating the displayed time of day (in the conventional twelve hour increment) is PM). - The
first display ring 70 is sized and shaped to be concentrically located about the primary display 28 (withsecond display ring 72 disposed between thefirst display ring 70 and the primary display 28), and includes UTC off-set indicial 110,various city indicia 112, andapertures 114. The first-fifth partial city rings 88 a-88 e also carry city indicia 116 a-116 e, and are sized and shaped such that upon final assembly below thefirst display ring 70, selective ones of the individual city indicia 116 a-116 e are selectively aligned with and visible through respective ones of theapertures 114. - Arrangement of the
particular city indicia 112 on the display ring relative to the particular UTC off-setindicia 110 as well as the particular city indicia 116 a-116 e displayed on each of the first-fifth partial city rings 88 a-88 e are premised upon various time zone locale groupings around the globe. As a point of reference,FIG. 4 illustrates daylight savings time protocols (for the year 2013) for common groupings of locales around the world, as well as the UTC off-set for multiple different locales of interest. For example, 2013 daylight savings time for the United States and Canada began Mar. 10, 2013 and ended Nov. 3, 2013, whereas Australia began on Oct. 6, 2013 and ends Apr. 7, 2014. It will be understood that different locales within each region may or may not adhere to the assigned daylight savings time protocol (e.g., in the United States, Hawaii and most of Arizona do not observe daylight savings time). Where followed, daylights savings entails a one-hour forward time shift at the start of the daylight savings time period and a one-hour backward time shift at the end of the daylight savings time period. The procedure by which daylight savings time is implemented can vary from region-to-region. For example, in the United States, the one-hour time shift occurs at 02:00 local time (i.e., 2:00 AM local time), whereas the European Union all shifts at 01:00 UTC (i.e., 1:00 AM UTC). Though complex, the daylight savings time protocols around the globe are well established. - The UTC off-set information reflected by
FIG. 4 is also well established, and reflects not only the difference or off-set (in hours) of each listed locale relative to UTC (e.g., Buenos Aires, Argentina has a UTC off-set of “−3” meaning that Buenos Aires is three hours “behind” UTC; in other words, at 05:00 (or 5:00 AM) UTC, it is 02:00 (or 2:00 AM) in Buenos Aires), but also that many of the listed locales do not follow daylight savings time. These locales are shown with bold letters inFIG. 4 . For the listed locales that do follow daylight savings time, the UTC off-set designations reflect that the UTC off-set applicable to a particular locale differs depending upon whether or not daylight savings time is in effect (e.g., Sydney, Australia has a UTC off-set of “+10” hours when daylight savings time is not in effect, and a UTC off-set of “+11” hours when daylight savings time is in effect). - With the above time zone groupings and UTC off-set conventions in mind, the
first display ring 70 is shown in greater detail inFIG. 5A . The UTC off-setindicia 110 follows the circular shape of thefirst display ring 70, and includes “UTC” and sequentially arranged (relative to the “UTC” designation) negative/positive integers that represent off-sets relative to UTC (i.e., “−10” through “−1” and “+1” through “+13”). The city indicia 112 includes a number of different city or other locale abbreviations that are each strategically arranged relative to selected ones of the UTC off-setindicia 110, directly implicating the UTC off-set assigned to the city/locale. For example, the UTC off-setindicia 110 includes “+9” (identified at 110 a) and thecity indicia 112 includes “TYO” (identified at 112 a). TheTYO city indicia 112 a is aligned with the +9 UTC off-setindicia 110 a. “TYO” is a well understood abbreviation for the city of Tokyo, Japan. Thus, because “TYO” is aligned with “+9”, a viewer readily understands that Tokyo has a +9 hour off-set relative to UTC (i.e., that Tokyo is 9 hours “ahead” of UTC). By way of further example, the UTC off-setindicia 110 further includes “−4” (identified at 110 b) and “−5” (identified at 110 c), and thecity indicia 112 includes “CCS” (identified at 112 b). TheCCS city indicia 112 b is aligned between the −4 and −5 UTC off-set indicia 110 b, 110 c. “CCS” is a well understood abbreviation for the city of Caracas, Venezuela. Thus, because “CCS” is aligned between “−4” and “−5”, a viewer readily understands that Caracas has a −4.5 hour off-set relative to UTC (i.e., that Caracas is 4.5 hours “behind” UTC). The cities or other locales represented by these andother city indicia 112 shown on thefirst display ring 70 are those that do not follow daylight savings time protocols and thus the UTC off-set for each city/locale will not change (as compared to cities/locales that do follow a daylight savings procedure as described above). Thus, thecity indicia 112 can be “permanently” displayed relative to the UTC off-setindicia 110 along thefirst display ring 70. The present disclosure is in no way limited to thecity indicia 112 shown. Other cities or locales (that do not otherwise follow daylight savings time) can be included with thecity indicia 112, other abbreviation formats can be employed, etc. - Respective ones of the
apertures 114 are aligned with certain ones of the UTC off-setindicia 110. For example, afirst aperture 114 a is aligned with the “−4” UTC off-set indicia 110 b. Theapertures 114 are each sized and circumferentially located such that upon final assembly, a section of a respective one of the first-fifth partial city rings 88 a-88 e (FIG. 3 ) is visible through the correspondingaperture 114. With this in mind, the first-fifth partial city rings 88 a-88 e are shown in greater detail inFIG. 5B . The city indicia 116 a-116 e includes a number of different city or other locale abbreviations, with the city indicia 116 a-116 e carried by the corresponding first-fifthpartial city ring 88 a-88 e representing a grouping of geographically close (in terms of time zone) cities/locales that each follow a daylight savings time protocol. For example, the city indicia 116 a of the firstpartial city ring 88 a includes “CAI” (identified at 116 a-1), a first “PAR” 116 a-2, a second “PAR” 116 a-3, a first “LON” 116 a-4, a second “LON” 116 a-5, and “RKV” 116 a-6. The designations 116 a-1-116 a-6 are well understood abbreviations for the cities of Cairo, Paris, London, and Reykjavik, respectively, and is each sized to be displayed through a corresponding one of theapertures 114 in thefirst display ring 70. The city indicia 116 a optionally includes redundant city/locale designations (e.g., the two “PAR” 116 a-2, 116 a-3 and the two “LON” 116 a-4, 116 a-5) for reasons made clear below. The cities implicated by the city indicia 116 b-116 e of the remaining partial city rings 88 b-88 e can follow a similar format (i.e., common grouping of cities/locales following daylight savings time and geographically proximate one another at least in terms of time zone), with some abbreviations being repeated for reasons made clear below. - Upon final assembly, the partial city rings 88 a-88 e underlie the
first display ring 70, arranged such that selected ones of the city indicia 116 a-116 e are visible through a corresponding one of theapertures 114. By rotating thefirst display ring 70 relative to one or more or all of the partial city rings 88 a-88 e and/or by automated rotation of one or more of all of the partial city rings 88 a-88 e relative to thefirst display ring 70, the particular city indicia 116 a-116 e visible through one or more or all of theapertures 114 will change. For example,FIG. 6A illustrates one possible arrangement of thefirst display ring 70 relative to the partial city rings 88 a-88 e (it being understood that the partial city rings 88 a-88 e are primarily hidden behind thefirst display ring 70 in the view ofFIG. 6A and are thus referenced generally). The partial city rings 88 a-88 e are arranged relative to thefirst display ring 70 such that a selected one of the city indicia 116 a-116 e is visible through respective ones of theapertures 114, and the so-displayed city indicia is aligned with a corresponding one of the UTC off-setindicia 110. For example, the firstpartial city ring 88 a is arranged relative to thefirst display ring 70 such that the second “PAR” city indicia 116 a-3 is visible through asecond aperture 114 b otherwise aligned with a “+1” UTC off-setindicia 110 d. A viewer readily understands this arrangement or display to indicate that Paris currently has a +1 hour off-set relative to UTC (i.e., that Paris is one hour “ahead” of UTC). The thirdpartial city ring 88 c is arranged relative to thefirst display ring 70 such that a first “CHI” city indicia 116 c-4 (also identified inFIG. 5B ) is visible through a third aperture 114 c otherwise aligned with the “−5” UTC off-set indicia 110 c. A viewer readily understands this arrangement or display to mean that Chicago currently has a −5 hour off-set relative to UTC (i.e., that Chicago is currently five hours “behind” UTC). -
FIG. 6B illustrates a second possible arrangement of thefirst display ring 70 relative to the partial city rings 88 a-88 e (that again are primarily hidden in the view ofFIG. 6B ). As compared to the arrangement ofFIG. 6A , the third and fifth partial city rings 88 c, 88 e have moved or rotated (about the central axis C) relative to thefirst display ring 70, whereas a relationship between the first, second and fourth partial city rings 88 a, 88 b, 88 d relative to thefirst display ring 70 has not changed. The change in relationship between the third and fifth partial city rings 88 c, 88 e relative to thefirst display ring 70 can be accomplished by moving thefirst display ring 70 and/or moving the third and fifth partial city rings 88 c, 88 e relative to one another. In the view ofFIG. 6B , the thirdpartial city ring 88 c is arranged relative to thefirst display ring 70 such that a second “CHI” city indicia 116 c-5 (also identified inFIG. 5B ) is visible through afourth aperture 114 d otherwise aligned with a “−6” UTC off-setindicia 110 e. A viewer readily understands this arrangement or display to mean that Chicago currently has a −6 hour off-set relative to UTC (i.e., that Chicago is currently six hours “behind” UTC). Notably, a relationship between the firstpartial city ring 88 a and thefirst display ring 70 has not changed between the views ofFIGS. 6A and 6B ; thus, in the view ofFIG. 6B , the second “PAR” city indicia 116 a-3 remains aligned with and visible through thesecond aperture 114 b otherwise aligned with the “+1” UTC off-setindicia 110 d. Again, a viewer readily understands this arrangement or display to indicate that Paris currently has a +1 hour off-set relative to UTC (i.e., that Paris is currently one hour “ahead” of UTC). - Returning to
FIG. 3 , thesecond display ring 72 is concentrically disposed between theprimary display 28 and thefirst display ring 70, with thesecond display ring 72 being rotatable relative to theprimary display 28 and thefirst display ring 70. Thesecond display ring 72 carries or displayshour indicia 120, consisting of numbers or letters that collectively represent a twenty-four hour day in sequential order. In some embodiments, thehour indicia 120 includes differentiators between midnight and noon (e.g., “MDNT” hour indicia 120 a and “NOON” hour indicia 120 b), with consecutive numbers 1-11 between the MDNT and NOON representing the hours between midnight and noon (e.g., thehour indicia 120 includes the number “1” (identified at 120 c) immediately adjacent (in the clockwise direction) the “MDNT” hour indicia 120 a and is thus readily understood to represent 1:00 AM; a second number “1” (identified at 120 d) is displayed immediately adjacent (in the clockwise direction) the “NOON” hour indicia 120 b and is thus readily understood to represent 1:00 PM). Depending on the mechanism employed, the direction of rotation may change and require the adjacent numbers to be incremented in the counter-clockwise direction. The hour indicia 120 can also assume a variety of other forms. - The
second display ring 72, and in particular thehour indicia 120 carried thereby, allows a viewer of thewatch assembly 46 to more quickly determine the current time in various locales around the globe without changing the current selected city or theprimary display 28 time. For example, and with reference toFIG. 7 , the hour andminute hands primary display 28 to indicate a current time of 10:00; the AM/PM indicia 106 visible at theprimary display 28 is “P”, thus confirming that the current time is 10:00 PM. With this in mind, thehour indicia 120 of thesecond display ring 72 is generally aligned with locales displayed at or through thefirst display ring 70, thus informing a viewer as to the corresponding current time in the displayed locales. For example, the “NOON” hour indicia 120 b is generally aligned with the “TYO”city indicia 112 a, readily informing a viewer that the current time in Tokyo is 12:00 noon. Notably, a viewer could alternatively calculate the current time in Tokyo by noting the “−5” UTC off-set indicia 110 c associated with the city to which the watch has been set as mentioned above (Chicago), and the “+9” UTC off-setindicia 110 a associated with Tokyo. Comparing these two UTC off-set values, a viewer is readily informed that Tokyo is 14 hours ahead of the locale to which the watch has been set; thus, adding 14 hours to the displayed current time of 10:00 PM results in 12:00 noon in Tokyo. Thesecond display ring 72 allows the viewer to more quickly ascertain this same information. By way of further example, the “1” (AM)hour indicia 120 c is generally aligned with the “RIO” city indicia 116 b-2 (also identified inFIG. 5B ) that is otherwise visible through afifth aperture 114 e, readily informing a viewer that the current time in Rio de Janeiro is 1:00 AM. - Returning to
FIG. 3 , thecontrol assembly 54 is operable to control movement of therear display assembly 52 components as well as components of the front display assembly 50 (apart from the primary display 28), and can assume a wide variety of forms. In general terms, thecontrol assembly 54 can include various gears, linkages, springs, or other mechanisms configured to interface with the front andrear display assemblies control assembly 54 is shown in greater detail inFIG. 8 (along with components of the rear display assembly 52). Thecontrol assembly 54 can include a movement sub-assembly 130 (drawn schematically in block form), ahand drive sub-assembly 132, movement couplers 134 (referenced generally), a time setpost 136, a date setpost 138, set gears 140 (referenced generally), control gears 142 (referenced generally), and apower supply 144. In general terms, thehand drive assembly 132 dictates movement of the hour, minute, and second hands 22-26 (FIG. 1A ), with operation of thehand drive assembly 132 being controlled by the movement sub-assembly 130 via themovement couplers 134. The time setpost 136 via affords user control over an arrangement of the hour andminute hands post 138 affords user control of the displayed date (and optionally AM/PM) via the set gears 140. The control gears 142 interface with corresponding components of therear display assembly 52, with movement of the control gears 142 being dictated by the movement sub-assembly 130. Finally, the power supply 144 (e.g., a battery or mechanical power/energy source such as a spring system as known to those skilled in the art of watch making) provides power to the movement sub-assembly 130. - The movement sub-assembly 130 includes conventional watch components and mechanisms (e.g., gears, springs, pawls, levers, etc.) known in the art for operating a watch. For example, the movement sub-assembly 130 can include an off-the-shelf watch control assembly available from ETA SA Swiss Watch Manufacturer of Grenchen, Switzerland. In addition, the movement sub-assembly 130 includes a controller apparatus 146 (referenced generally). The
controller 146 can be any form of mechanical, digital or computer-type controller (e.g., a programmable logic controller) that optionally includes a memory and is programmed (or programmable) to prompt movement of thegears controller 146 are described in greater detail below. Such control mechanisms can also employ standard timing control components such as quartz crystals with electromagnetic output or purely mechanical elements. - The
hand drive assembly 132 can also be of a conventional design commonly used with watches, and includes drive shafts or pins that are configured to be individually linked to respective ones of the hands 22-26 (FIG. 1A ), along with individual gears linked to respective ones of the drive shafts. The gears, in turn, are linked to themovement couplers 134 that are configured for connection to corresponding mechanisms (not shown) provided with the movement sub-assembly 130 such that the movement sub-assembly 130 controls movement of the hands 22-26 via thehand drive assembly 132. As with other mechanisms associated with thecontrol assembly 54, themovement couplers 134 can assume a wide variety of forms as is readily apparent to one of skill. In some embodiments, themovement couplers 134 can include anhour hand coupler 150 a, a minute hand coupler 150 b, and a second hand coupler 150 c. - The time set
post 136 is of a conventional type, and includes ashaft 152 and acrown 154. Theshaft 152 is sized and shaped to interface with (e.g., with rotation of the shaft 152) one or both of the movement sub-assembly 130 (via one or more mechanisms (not shown) provided with the movement sub-assembly) and themovement couplers 134, for example at anend 155 of theshaft 152. Thecrown 154 is attached to theshaft 152 and is configured to facilitate user actuation (e.g., pulling and/or rotation) of the time setpost 136. - The date set
post 138 is of a conventional type, and includes ashaft 156 and acrown 158. Theshaft 156 is sized and shaped to interface with (e.g., with rotation of the shaft 152) one or both of the movement sub-assembly 130 (via one or more mechanisms (not shown) provided with the movement sub-assembly 130) and the set gears 140, for example at anend 159 of theshaft 156. Thecrown 158 is attached to theshaft 156 and is configured to facilitate user actuation (e.g., pulling and/or rotation) of the date setpost 138. - The set gears 140 include first-fourth year gears 160 a-160 d, a
month gear 162, adate gear 164 and an AM/PM gear 166. The first-fourth year gears 160 a-160 d are configured to interface with corresponding ones of the first-fourth year rings 80 a-80 d such that rotation of theyear gear 160 a-160 d prompts rotation of the corresponding year ring 80 a-80 d. Themonth gear 162 has a similar relationship with themonth ring 82, as does thedate gear 164 with thedate ring 84, and the AM/PM gear 166 with the AM/PM ring 86. A wide variety of other mechanical and/or electromechanical components can alternatively be employed to control movement of one or more of the year rings 80 a-80 d, themonth ring 82, thedate ring 84 and/or the AM/PM ring 86. Regardless, the set gears 140 (or other device) are each linked, directly or indirectly, to the movement sub-assembly 130 and the date setpost 138 for reasons made clear below. - The control gears 142 include first-fifth city gears 170 a-170 e and a second
display ring gear 172. The first-fifth city gears 170 a-170 e are configured to interface with corresponding ones of the first-fifth partial city rings 88 a-88 e such that rotation of thecity gear 170 a-170 e prompts movement (i.e., rotation about the central axis C (FIG. 1A ) of the watch assembly 46) of the correspondingpartial city ring 88 a-88 e. The seconddisplay ring gear 172 has a similar relationship with the second display ring 72 (FIG. 3 ). A wide variety of other mechanical components can alternatively be employed to control movement of one or more of the partial city rings 88 a-88 e and/or thesecond display ring 72. Regardless, the control gears 142 (or other device) are each linked, directly or indirectly, to the movement sub-assembly 130 for reasons made clear below. - Arrangement of components of the
control assembly 54 relative to therear display assembly 52 and thesecond display ring 72 is illustrated inFIG. 9A (in which the movement sub-assembly 130 and thepower source 144 are removed for ease of understanding). Each of the first-fifth city gears 170 a-170 e is connected to or meshes with a respective one of the first-fifth partial city rings 88 a-88 e (e.g., each of the first-fifth partial city rings 88 a-88 e forms a toothed back surface (not shown) that meshes with teeth (not shown) of thecorresponding city gear 170 a-170 e). The seconddisplay ring gear 172 is similarly connected to or meshes with thesecond display ring 170. The time setpost 136 is connected to themovement couplers 134 that are in turn connected (directly or indirectly) to thehand drive sub-assembly 132. For example, the time setpost 136 can be articulated transversely (relative to a center point of the assembly), bringing theend 155 of the time setpost shaft 152 into selective engagement with a corresponding one of thehour hand coupler 150 a, the minute hand coupler 150 b, or the second hand coupler 150 c. The first-fourth year gears 160 a-160 d are connected to or meshed with respective ones of the first-fourth year rings 80 a-80 d such that rotation of theyear gear 160 a-160 d would cause rotation of the corresponding year ring 80 a-80 d. Themonth gear 162 has a similar relationship with themonth ring 82, as does thedate gear 164 with thedate ring 84, and the AM/PM gear 166 with the AM/PM ring 86. The date setpost 138 is selectively connected to or meshed with each of the year gears 160 a-160 d, themonth gear 162, thedate gear 164 and the AM/PM gear 166. For example, the date setpost 138 can be articulated transversely (relative to a center point of the assembly), bringing theend 159 of the date setpost shaft 156 into selective engagement with a corresponding one of the year gears 160 a-160 d, themonth gear 162, thedate gear 164 and the AM/PM gear 166. -
FIG. 9B illustrates, in simplified form, an alternative configuration of control gears 140′, and in particular first-fifth city gears 170 a′-170 e′. The first-fifth city gears 170 a′-170 e′ are concentrically arranged, each providing a toothed surface configured to mesh with teeth provided on a rear face of each the partial city rings 88 a-88 e (two of which are shown in enlarged form inFIG. 9B ). The partial city rings 88 a-88 e and the first-fifth city gears 170 a′-170 e′ are constructed and arranged such that eachpartial city ring 88 a-88 e interfaces with or is acted upon a corresponding, respective one of the first-fifth city gears 170 a′-170 e′. - Returning to
FIG. 3 , thebezel assembly 56 includes abezel 180 and aspring 182. Thebezel 180 is configured to maintain various components of thedisplay assemblies control assembly 54 relative to one another, as well as to facilitate user interaction with at least thefirst display ring 70 as described below. In this regard, thespring 182 biases thebezel 180 to a disengaged position relative to thefirst display ring 70. - Final assembly of the
watch 20 is shown inFIGS. 10A and 10B . For ease of explanation, thewatch 20 is shown with thefront cover 44 removed. Theback cover 42 and thebezel 180 are coupled to opposite sides of thecase 40, with thebezel spring 182 biasing thebezel 180 to the normal position shown. The movement sub-assembly 130 and thepower supply 144 are supported against theback cover 42. The time set post 136 (hidden inFIG. 10A and shown partially in 10B) and the date setpost 138 extend through thecase 40 to the arrangement described above, with the correspondingcrowns 154, 158 (thecrown 154 of the time setpost 136 being hidden in the views ofFIGS. 10A and 10B ) being located outside of thecase 40 and available to be manipulated by a user. Thefirst display ring 70 is supported within arim 190 of thebezel 180. Thesecond display ring 72 is supported concentrically within thefirst display ring 70 in a manner permitting thesecond display ring 72 to rotate relative to the first display ring 70 (and vice-versa), for example by the second display ring gear 172 (hidden inFIGS. 10A and 10B , but shown inFIG. 8 ). Theprimary display 28 is supported concentrically within the second display ring 72 (in a manner permitting thesecond display ring 172 to rotate relative to the primary display 28). The hands 22-26 are arranged over theprimary display 28 and are coupled to thehand drive assembly 132 that in turn is connected to the movement sub-assembly 130. The first-fifth partial city rings 88 a-88 e underlie thefirst display ring 70, each circumferentially aligned with thefirst display ring 70 in a manner permitting the first-fifth partial city rings 88 a-88 e to move or rotate about the central axis C independent of thefirst display ring 70. For example, thefirst city gear 170 a (that otherwise supports the firstpartial city ring 88 a) and thefourth city gear 170 d (that otherwise supports the fourthpartial city ring 88 d) are visible in the view ofFIG. 10A . The AM/PM ring 86 underlies, and is rotatable relative to, theprimary display 28, for example supported by the AM/PM gear 166. Thedate ring 84, themonth ring 82, and the year rings 80 a-80 d similarly underlie, and are rotatable relative to, the primary display, for example supported by the corresponding one of the set gears 140 (referenced generally). - As mentioned above, the
watch 20 includes the computer-type controller 146 (FIG. 8 ) programmed to perform various operations in accordance with principles of the present disclosure, including automated shifting or movement of components relative to one another in response to, for example, a user indicating a desired current time, date, locale or other setting to thewatch 20 and/or determined occurrence of a daylight savings time event. Several of the optional operational programs automatically effectuated by thecontroller 146 in some embodiments are provided below, it being understood that the present disclosure is not limited to any one or more or all such operations. - With initial reference to
FIG. 11A , thewatch 20 has been set to display a current time of 1:00 PM, a current date of Jun. 11, 2013, and a current locale of Tokyo (or any other locale that is in the same time zone as Tokyo). The current time (i.e., arrangement of the hour andminute hands 22, 24) and the current date are “entered” by a user via actuation of the time and/or date setposts first display ring 70 until the locale of interest is aligned with the twelve o'clock position. For example, thebezel 180 can be lifted by the user so as to engage thefirst display ring 70 and then rotated to bring the desired locale to the twelve o'clock position. In some embodiments, thewatch 20 can include anoptional selection indicator 200 that highlights to a user which city/locale has been selected as the current locale. Theoptional selection indicator 200, where provided, can be located at various positions, such as the twelve o'clock position as shown, the six o'clock position, etc. Regardless, information relating to the set current time, current date and current locale is identified and acted upon by the controller 146 (FIG. 8 ), with thecontroller 146 in turn operating to arrange thesecond display ring 72 and the partial city rings 88 a-88 e in an appropriate fashion. For example, in the view ofFIG. 11A , thesecond display ring 72 has been rotated to align the “1” (PM)hour indicia 120 d (hidden behind theminute hand 24 inFIG. 11A ) with the 12 o'clock position. Further, thecontroller 146 is programmed with daylight savings time protocols throughout the world, and locates the partial city rings 88 a-88 e relative to thefirst display ring 70 based upon reference to the set current date so that correct information is displayed by thewatch 20. - Although all the cities/locales implicated by the partial city rings 88 a-88 e practice daylight savings time, on Jun. 11, 2013, daylight savings time is in effect for some of the cities/locales and is not in effect in others. For example, daylight savings time is in effect in Chicago and as such, Chicago is five hours “behind” UTC; the
controller 146 has thus prompted movement of the thirdpartial city ring 88 c relative to thefirst display ring 70 such that the first “CHI” city indicia 116 c-4 is aligned with and visible through the third aperture 114 c associated with the “−5” UTC off-set indicia 110 c. Further, an “11” (PM) hour indicia 120 e of thesecond display ring 72 is aligned with the visible “CHI” city indicia 116 c-4, informing the viewer that it is currently 11:00 PM in Chicago. By way of further example, daylight savings time is not in effect in Sydney on Jun. 11, 2013 and as such, Sydney is 10 hours “ahead” of UTC; thecontroller 146 has thus prompted movement of the fifthpartial city ring 88 e relative to thefirst display ring 70 such that a second “SYD” city indicia 116 e-3 is aligned with and visible through a sixth aperture 114 f that is otherwise aligned with a “+10” UTC off-set indicia 110 f (and with the “2” (PM) hour indicia 120 f of the second display ring 72). - The
watch 20 operates in a conventional manner, with the hands 22-26 and the AM/PM ring 86 moving to accurately display the current time of the selected city; the displayed current date information similarly changes in a conventional manner, with theday ring 84, themonth ring 82 and the year rings 80 a-80 d being prompted to automatically, either by standard watch mechanisms or as dictated by thecontroller 146. Thecontroller 146 tracks the current date and is programmed to alter some or all of the partial city rings 88 a-88 e relative to the first display ring 70 (and/or vice-versa) when the current date implicates a change in daylight savings time in one or more locales associated with the partial city rings 88 a-88 e. For example,FIG. 11B is a view of thewatch 20 ofFIG. 11A displaying a current time of 1:00 PM but at a later date in time. The user has not “entered” any new settings into thewatch 20 between the views ofFIGS. 11A and 11B (e.g., the current locale setting of Tokyo has not changed); instead, the displayed current date has progressed to Dec. 11, 2013. - Comparing
FIG. 11B (Dec. 11, 2013) withFIG. 11A (Jun. 11, 2013), it will be recalled that Tokyo does not practice daylight savings time; thus, the difference in dates (Jun. 11, 2013 ofFIG. 11A vs. Dec. 11, 2013 ofFIG. 11B ) does not cause thecontroller 146 to move or rotate thefirst display ring 70 or thesecond display ring 72. However, thecontroller 146 has automatically prompted the partial city rings 88 a-88 e to move pursuant to a programmed protocol. For example, on Dec. 11, 2013, daylight savings time is not in effect in Chicago and as such, Chicago is now six hours “behind” UTC; thecontroller 146 has thus prompted automatic movement of the thirdpartial city ring 88 c relative to thefirst display ring 70 such that the “CHI” city indicia 116 c-5 is aligned with and visible through thefourth aperture 114 d, otherwise aligned with the “−6” UTC off-setindicia 110 e, and with a “10” (PM) hour indicia 120 g of thesecond display ring 72. Thus, the user is correctly informed that it is currently 10:00 PM in Chicago. By way of further example, daylight savings time is in effect in Sydney on Dec. 11, 2013 and as such, Sydney is now 11 hours “ahead” of UTC; thecontroller 146 has thus prompted movement of the fifthpartial city ring 88 e relative to thefirst display ring 70 such that the “SYD” city indicia 116 e-2 is aligned with and visible through the aperture 114 g associated with the “+11” UTC off-setindicia 110 g (and with a “3” (PM) hour indicia 120 h of the second display ring 72). Thus, the user is correctly informed that it is currently 3:00 PM in Sydney. - Another example of an operation automatically performed by the
watch 20 in accordance with principles of the present disclosure includes automatically changing the displayed time upon a user entering a new locale setting. For example, thewatch 20 inFIG. 11B has been set such that a current displayed setting is 1:00 PM Tokyo on Dec. 11, 2013.FIG. 12 illustrates thewatch 20 ofFIG. 11B , immediately after thefirst display ring 70 has been rotated by a user (e.g., via the bezel 180) to bring the “MOW”city indicia 112 c within the selection indicator 200 (i.e., thefirst display ring 70 has been rotated to locate the “MOW”city indicia 112 c at the twelve o'clock position). “MOW” is readily understood to be an abbreviation for the city of Moscow, Russia. This hypothetical scenario might occur, for example, were the user to have traveled from Tokyo to Moscow on Dec. 11, 2013, and upon arriving, simply rotated thefirst display ring 70 to locate “MOW” in theselection indicator 200. This rotation may or may not require lifting thebezel 180 and holding thebezel 180 in the lifted position during rotation. Alternatively, this rotation could be accomplished by rotation of an additional crown intended for that purpose. Once the new locale has been “entered” by the user, thecontroller 146 automatically recognizes the change the time zone setting. ComparingFIG. 12 toFIG. 11B , then, thecontroller 146 has automatically prompted thehour hand 22 to rotate to a position indicative of 8:00, and the AM/PM ring 86 to display “A” at theprimary display 28. Thus, the display of thewatch 20 has been automatically changed to correctly indicate that the current time (in the Moscow time zone) is 8:00 AM (and as a point of confirmation, in the view ofFIG. 11B (i.e., just prior to user-initiated movement of the first display ring 70), an “8” (AM) hour indicia 120 i provided with thesecond display ring 72 is aligned with the “MOW”city indicia 112 c). Thecontroller 146 has also automatically prompted thesecond display ring 72 to rotate in a corresponding fashion, aligning the “8” (AM) hour indicia 120 i with the “MOW”city indicia 112 c at the twelve o'clock position. Finally, thecontroller 150 has prompted the partial city rings 88 a-88 e to move in accordance with the sensed movement of thefirst display ring 70, maintaining the same city indicia-to-aperture 114/UTC off-setindicia 110 relationships (e.g., the designation inFIG. 11B that Chicago has a UTC off-set of “−6” is duplicated inFIG. 12 ). Alternatively, all of the partial city rings 88 a-88 e can be coupled mechanically to thefirst display ring 70 such that they all move in concert when the user moves “MOW” to the selected city position. - With the hypothetical of the previous paragraph, the “new” current locale being entered or set to the watch 20 (i.e., Moscow) was carried or permanently displayed on the
first display ring 70. In other examples, the controller is programmed to perform similar, automated operations under circumstances where new current locale being entered by the user is provided on one of the partial city rings 88 a-88 e that underlie thefirst display ring 70. Further, the controller can be programmed to effectuate a change in the displayed date under circumstances where the entered change in locale implicates a change in date. For example, thewatch 20 as set as inFIG. 11A displays a current time of 1:00 PM in Tokyo (or other locale in the same time zone as Tokyo) on Jun. 11, 2013.FIG. 13 illustrates thewatch 20 ofFIG. 11A immediately after user-prompted rotation of thefirst display ring 70. In particular, thefirst display ring 70 has been rotated to bring the “CHI” city indicia 116 c-4 (otherwise carried by the thirdpartial city ring 88 c) within theselection indicator 200. In this regard, the partial city rings 88 a-88 e can be linked to thefirst display ring 70 such that when thefirst display ring 70 is lifted and rotated, the partial city rings 88 a-88 e move in tandem with thefirst display ring 70 and thebezel 180. Alternatively, thecontroller 146 can be programmed to automatically prompt movement of the partial city rings 88 a-88 e in tandem with thefirst display ring 70. Regardless, the “CHI” city indicia 116 c-4 is entered as the current locale in the arrangement ofFIG. 13 . As a point of reference, on Jun. 11, 2013, Chicago is fourteen hours “behind” Tokyo; thus 1:00 PM on Jun. 11, 2013 in Tokyo corresponds with 11:00 PM on Jun. 10, 2013 in Chicago. The controller is programmed with this information, and upon recognizing that Chicago has been entered as the set locale, automatically prompts movement of thehour hand 22 to indicate 11:00, movement of the AM/PM ring 86 to display “P”, and movement of thedate ring 84 to display “10”. - Another operation programmed to and automatically performed by the
watch 20 in some embodiments relates to automated adjustment of the displayed information upon occurrence of a daylight savings time event, and in particular the start of daylight savings time, in the city/locale to which thewatch 20 has been set. For example,FIG. 14A shows thewatch 20 displaying a current time of 1:59:59 AM (i.e., thehour hand 22 is approximately aligned with the 2 o'clock position of the primary display 28) on Mar. 10, 2013 for the set or selected city of Chicago. As highlighted within theselection indicator 200, at this exact moment in time, the thirdpartial city ring 88 c is arranged relative to thefirst display ring 70 such that the second “CHI” city indicia 116 c-5 is aligned with, and visible through, theaperture 114 d that is otherwise aligned with the “−6” UTC off-setindicia 110 e. Thus, at the point in time ofFIG. 14A , a viewer understands that Chicago is six hours “behind” UTC. Further, thesecond display ring 72 is arranged relative to thefirst display ring 70 such that the “2” (AM) hour indicia 120 j is aligned with theaperture 114 d (and thus the displayed “CHI” city indicia 116 c-5). - The daylight savings time protocols followed by Chicago dictate that at 2:00:00 AM on Mar. 10, 2013, a one hour forward time shift occurs.
FIG. 14B illustrates thewatch 20 ofFIG. 14A three seconds later in time, and highlights automated operation in response to this daylight savings time event. Thecontroller 146 provided with thewatch 20 is programmed to recognize the occurrence of the daylight savings time event and effectuate various watch component movements immediately following the event. ComparingFIG. 14B withFIG. 14A , thecontroller 146 has prompted thehour hand 22 to rotate relative to theprimary display 28, and is now approximately aligned with the 3 o'clock position of theprimary display 28. Further, thefirst display ring 70 has been prompted to rotate relative to theprimary display 28, aligning the “−5” UTC off-set indicia 110 c, and the corresponding aperture 114 c, within theselection indicator 200. The thirdpartial city ring 88 c has been prompted to rotate relative to thefirst display ring 70, aligning the first “CHI” city indicia 116 c-4 with the aperture 114 c. The remaining partial city rings 88 a, 88 b, 88 d, 88 e have been prompted to rotate in tandem with thefirst display ring 70. Finally, thesecond display ring 72 has been prompted to rotate relative to theprimary display 28, arranging a “3” (AM)hour indicia 120 k at the 12 o'clock position (i.e., aligned with the selection indicator 200). - As evidenced by the above explanations, the user is not required to make any manual adjustments to the
watch 20 in response to the described daylight savings time event. Thewatch 20 automatically and correctly transitions to the display ofFIG. 14B whereby the current time is correctly displayed as 3:00:02 AM on Mar. 10, 2013 for the selected or set city of Chicago. The “−5” UTC off-set indicia 110 c is aligned with the displayed “CHI” city indicia 116 c-4, and accurately reflects that Chicago is now five hours “behind” UTC. The “3” (AM)hour indicia 120 k is correctly aligned with the displayed “CHI” city indicia 116 c-4. Notably, thewatch 20 is programmed to correctly account for the fact that while a one hour forward time shift has been effectuated in Chicago (at 2:00 AM on Mar. 10, 2013), most other locales around the world do not experience that same one hour forward time shift at the same time. By prompting the partial city rings 88 a, 88 b, 88 d, 88 e (i.e., the partial city rings apart from the thirdpartial city ring 88 c that otherwise carries the “CHI” city indicia) to move in tandem with thefirst display ring 70, the display of bothFIGS. 14A and 14B correctly reflect that Paris (e.g., the “PAR” city indicia) remains one hour “ahead” of UTC (via alignment of the “PAR” city indicia 116 a-3 with theaperture 114 b corresponding the with the “+1” UTC off-sentindicia 110 d) and that it is currently 9:00 AM in Paris (via alignment of the “9”AM hour indicia 120 d carried by thesecond display ring 72 with the visible “PAR” city indicia 116 a-3). - Another operation programmed to and automatically performed by the
watch 20 in some embodiments relates to automated adjustment of the displayed information upon occurrence of a daylight savings time event, and in particular the end of daylight savings time, in the city/locale to which thewatch 20 has been set. For example,FIG. 15A shows thewatch 20 displaying a current time of 1:59:59 AM (i.e., thehour hand 22 is approximately aligned with the 2 o'clock position of the primary display 28) on Oct. 26, 2013 for the set or selected city of London. As highlighted within theselection indicator 200, at this exact moment in time, the firstpartial city ring 88 a is arranged relative to thefirst display ring 70 such that the first “LON” city indicia 116 a-4 is aligned with, and visible through, theaperture 114 b that is otherwise aligned with the “+1” UTC off-setindicia 110 d. Thus, at the point in time ofFIG. 15A , a viewer understands that London is one hour “ahead” of UTC. Further, thesecond display ring 72 is arranged relative to thefirst display ring 70 such that the “2” (AM) hour indicia 120 j is aligned with theaperture 114 b (and thus the displayed “LON” city indicia 116 a-4). - The daylight savings time protocols followed by London dictate that at 1:00:00 AM UTC (i.e., 2:00:00 AM London) on Oct. 26, 2013, a one hour backward time shift occurs.
FIG. 15B illustrates thewatch 20 ofFIG. 15A three seconds later in time, and highlights automated operation in response to this daylight savings time event. The controller provided with thewatch 20 is programmed to recognize the occurrence of the daylight savings time event and effectuate various watch component movements immediately following the event. ComparingFIG. 15B withFIG. 15A , the controller has prompted thehour hand 22 to rotate relative to theprimary display 28, and is now approximately aligned with the 1 o'clock position of theprimary display 28. Further, thefirst display ring 70 has been prompted to rotate relative to theprimary display 28, aligning the “UTC” UTC off-set indicia 110 h, and thecorresponding aperture 114 h, within theselection indicator 200. The firstpartial city ring 88 a has been prompted to rotate relative to thefirst display ring 70, aligning the second “LON” city indicia 116 c-5 with theaperture 114 h. The remaining partial city rings 88 b-88 e have been prompted to rotate in tandem with thefirst display ring 70. Finally, thesecond display ring 72 has been prompted to rotate relative to theprimary display 28, arranging the “1” (AM)hour indicia 120 c at the 12 o'clock position (i.e., aligned with the selection indicator 200). - As evidenced by the above explanations, the user is not required to make any manual adjustments to the
watch 20 in response to the described daylight savings time event. Thewatch 20 automatically and correctly transitions to the display ofFIG. 15B whereby the current time is correctly displayed as 1:00:02 AM on Oct. 26, 2013 for the selected or set city of London. The “UTC” UTC off-set indicia 110 h is aligned with the displayed “LON” city indicia 116 a-5, and accurately reflects that London is now at UTC. The “1” (AM)hour indicia 120 c is correctly aligned with the displayed “LON” city indicia 116 a-5. Notably, thewatch 20 is programmed to correctly account for the fact that while a one hour backward time shift has been effectuated in London (at 2:00 AM on Oct. 26, 2013), many other locales around the world do not experience a one hour backward time shift at the same time. By prompting the partial city rings 88 b-88 e (i.e., the partial city rings apart from the firstpartial city ring 88 a that otherwise carries the “LON” city indicia) to move in tandem with thefirst display ring 70, the display of bothFIGS. 15A and 15B correctly reflects, for example, that Sydney (e.g., the “SYD” city indicia 116 e-2) remains eleven hours “ahead” of UTC (via alignment of the “SYD” city indicia 116 e-2 with the aperture 114 g corresponding the with the “+11” UTC off-sentindicia 110 g) and that it is currently 12:00 noon in Sydney (via alignment of the “NOON” hour indicia 120 b carried by thesecond display ring 72 with the visible “SYD” city indicia 116 e-2). - The world watches of the present disclosure can be programmed to perform multiple other operations via prompted manipulation of the various hands, rings and partial rings to automatically effectuate a change in the displayed current time, displayed current date, displayed UTC off-set relative to cities/locales of interest, and/or displayed hour indicia relative to cities/locales of interest. Further, while the
watch 20 has been described as employing a series of concentrically arranged rings or partial rings, in other embodiments, a less-than fully concentric configuration is provided. For example,FIG. 16A is a front view of another embodiment watch 300 in accordance with principles of the present disclosure. Thewatch 300 is akin to thewatch 20 described above, and generally includes a controller apparatus (not shown) configured (e.g., programmed) to automatically effectuate changes in information displayed at a face of thewatch 300 in response to various events (e.g., a daylights saving time event, user-prompted change in set time, date or selected time zone city). Thewatch 300 further includes the hour, minute and second hands 22-26, thebezel 180, thefirst display ring 70, thesecond display ring 72, and the partial city rings 88 a-88 d as described above. A circular-shapedprimary display 302 is also provided, with the hands 22-26 moving relative to the hour indicia on theprimary display 302 to convey current time information (e.g., in the view ofFIG. 16A , the hands are indicating a current time of approximately 10:10). Apertures 304-310 are formed through theprimary display 302 and through which year, month, day, and AM/PM information is displayed. -
FIG. 16B provides a view of thewatch 300 with thefirst display ring 70 and theprimary display 302 removed, and reveals that thewatch 300 further includes the partial city rings 88 a-88 e as described above. Further, thewatch 300 includes aday ring 312, amonth ring 314, year rings 316 (collectively identified), and an AM/PM ring 318. As compared to previous embodiments, and with cross-reference betweenFIGS. 16A and 16B , while theday ring 312 is concentrically arranged relative to the first and second display rings 70, 72, the month, year and AM/PM rings 314-318 are not. Instead, a tangential relationship is established. Each of the month, year and AM/PM rings 314-318 rotate about a corresponding center point that is off-set from a center point of the first and second display rings 70, 72. For example, themonth ring 314 is configured such that upon final assembly, individual months (or abbreviations indicative of each month of the year) are selectively displayed through the correspondingaperture 306 in theprimary display 302. Similar relationships are established by the year and AM/PM rings 316, 318 relative to theapertures - Another embodiment of a
world watch 400 in accordance with principles of the present disclosure is shown inFIGS. 17A and 17B (with the view ofFIG. 17B illustrating thewatch 400 with various front face display components removed). Thewatch 400 is akin to thewatch 20 described above, and generally includes a controller apparatus (not shown) configured (e.g., programmed) to automatically effectuate changes in information displayed at a face of thewatch 400 in response to various events (e.g., a daylights saving time event, user-prompted change in set time, date or selected time zone city). Thewatch 400 includes the hour, minute and second hands 22-26 and thebezel 180 as described above. In addition, thewatch 400 includes aprimary display 402 and a display ring 404. Theprimary display 402 may or may not include or display hour indicia, with the hands 22-26 moving relative to theprimary display 402 to convey current time information (e.g., in the view ofFIG. 17A , thehands primary display 402 forms several openings or apertures through which indicia on components located below theprimary display 402 are selectively visible. For example, and as described in greater detail below, theprimary display 402 forms ayear aperture 406, amonth aperture 408, an upper date and AM/PM aperture 410, and a lower date and AM/PM aperture 412. - The display ring 404 is akin to the
first display ring 70 described above, and is connected to thebezel 180 so as to be rotatable about theprimary display 402. The display ring 404 includes or displays city indicia 414 (referenced generally). The cities implicated by thecity indicia 414 of the display ring 404 represent locales that do not follow or observe daylight savings time. The display ring 404 further defines city apertures 416 a-416 c for reasons made clear below. -
FIG. 17B provides a view of thewatch 400 with theprimary display 402 and the display ring 404 removed, although an outlined representation of the various apertures 406-412 and 416 a-416 c is provided.FIG. 17B reveals that thewatch 400 further includes partial city rings 420 a-420 c, year rings 422 (collectively identified), amonth ring 424, upper date rings 426 (collectively identified), an upper AM/PM ring 428, lower date rings 430 (collectively identified) and a lower AM/PM ring 432. With cross-reference betweenFIGS. 17A and 17B , the first-third partial city rings 420 a-420 c are circumferentially aligned with a respective one of the first-third city apertures 416 a-416 c. Thus, various ones of thecity indicia 434 carried on or displayed by the partial city rings 420 a-420 c are selectively visible through a corresponding one of the city apertures 416 a-416 c depending upon a rotational position of the particular city ring 420 a-420 c relative to the display ring 404 (and thus relative to the city apertures 416 a-416 c). The partial city rings 420 a-420 c are linked (directly or indirectly, mechanically or electromechanically) to a user actuator, for example thebezel 180, so that a user can effectuate a change in a rotational position of one or all of the partial city rings 420 a-420 c relative to the display ring 404 (and thus a change in the displayedcity indicia 434 relative to the corresponding city aperture 416 a-416 c). Further, the partial city rings 420 a-420 c can be linked (directly or indirectly, mechanically or electromechanically) to a controller (not shown) provided with thewatch 400 and pre-programmed as described above; the controller can selectively effectuate changes in the rotational position of one or more of the partial city rings 420 a-420 c relative to the display ring 404 (and thus relative to the corresponding city aperture 416 a-416 c) in response to various user inputs and/or daylight savings time events across the globe. - In addition, the controller is programmed to “recognize”, at least in part, a designated city as having been “selected” by a user, and to base various daylight savings time operations off of the selected city. Commensurate with previous embodiments, a user can designate or select a desired city by manipulating the display ring 404 and/or the partial city rings 420 a-420 c to align the
particular city indicia FIG. 17A , a relationship of the city indicia 414 (of the display ring 404) relative to the city apertures 416 a-416 c (and thus relative to thecity indicia 434 of the partial city rings 420-420 c) is such that in many instances, two cities can be aligned at the twelve o'clock position (i.e., one of thecity indicia 414 of the display ring 404 and one of thecity indicia 434 of partial city rings 420 a-420 c). For example, inFIG. 17A , thecity indicia 434 of the firstpartial city ring 420 a of “CHICAGO” is aligned with the twelve o'clock position, as is thecity indicia 414 of the display ring 404 of “BANGKOK”. Relative to the twelve o'clock position, then, the aligned cities can be referred to as an upper designatedcity 440 and a lower designatedcity 442. With the arrangement ofFIG. 17A , the upper designatedcity 440 is “CHICAGO”, and the lower designatedcity 442 is “BANGKOK”. In other possible arrangements of thewatch 400, the upper designatedcity 440 can be provided by thecity indicia 414 of the display ring 404, and the lower designatedcity 442 provided by thecity indicia 434 of one of the partial city rings 420 a-420 c. - Regardless, the upper and lower designated
cities cities watch 400 such that the city corresponding (from a time zone perspective) to the user's current locale (or the city the user otherwise desires to “select”) is at the twelve o'clock position. Thewatch 400 will self-prompt the corresponding, twelve hours out-of-phase companion city to also be aligned with the twelve o'clock position. For example, with the arrangement ofFIG. 17A , the user may have intended to select “CHICAGO” and thus manipulated thewatch 400 such that “CHICAGO” was aligned with the twelve o'clock position (and thus serving as the upper designated city 440). Depending upon the current date and time (including AM/PM designation) supplied to the watch 400 (i.e., as currently displayed or as inputted by a user) as described below, the watch controller determines the corresponding, twelve hour out-of-phase city and prompts alignment of the so-determined city with the twelve o'clock position. For example, with the arrangement ofFIG. 17A , on Apr. 23, 2014, Bangkok is twelve hours out-of-phase with Chicago; the watch controller has thus prompted an orientation of the display ring 404 to align “BANGKOK” with the twelve o'clock position (and thus serving as the lower designated city 440). It will be understood that at other periods of the calendar year, a different city will be twelve hours out-of-phase with Chicago (i.e., Dhaka, Bangladesh); the controller recognizes the appropriate twelve hours out-of-phase city and prompts its display at the twelve o'clock position. This same scenario would automatically occur had the user intended to select BANGKOK as the city of interest (i.e., after the user had manipulated thewatch 400 to locate “BANGKOK” at the twelve o'clock position, the watch controller would automatically prompt the partial city rings 420 a-420 c such that “CHICAGO” was also displayed at the twelve o'clock position). Thewatch 400 can include other features that further highlight a “selected” city to a user as with previous embodiments. Further, the controller can be programmed such that certain user inputs or actuations serve to designate that a particular city has been selected. Regardless, thewatch 400 can display information that allows a viewer to quickly discern time and/or date differences between the upper and lower designatedcities - More particularly, the year rings 422 are aligned with the
year aperture 406 and are operated as with previous embodiments. Similarly, themonth ring 424 is aligned with themonth aperture 408 and is operated as with previous embodiments. The upper date rings 426 and the upper AM/PM ring 428 are aligned with the upper date and AM/PM aperture 410. The upper date rings 426 and the upper AM/PM ring 428 are operated as described above, and provide date and AM/PM information for the upper designatedcity 440. For example, in the view ofFIG. 17A , the upper date and AM/PM rings 426, 428 indicate that the current time and date in the upper designatedcity 440 of “CHICAGO” are 10:10 PM on Apr. 23, 2014. The lower date rings 430 and the lower AM/PM ring 432 are aligned with the lower date and AM/PM aperture 412. The lower date rings 430 and the secondary AM/PM ring 432 are operated as described above, and provide date and AM/PM information for the lower designatedcity 442. For example, in the view ofFIG. 17A , the lower date and AM/PM rings 430, 432 indicate that the current time and date in the lower designatedcity 442 of Bangkok are 10:10 AM on Apr. 24, 2014. As with previous embodiments, the controller is programmed to control operation of the various rings 422-432 in accordance with preprogrammed information or algorithms. - It will be recognized that the
watch 400 could be arranged such that a city or locale following a non-integer time zone off-set (relative to UTC) is aligned with the twelve o'clock position (e.g., Caracas, Tehran, etc.). Under these circumstances, the so-selected city will serve as the lower designatedcity 442. No counterpart, twelve hour out-of-phase companion city is available, such that only one city will be aligned with the twelve o'clock position. The information displayed at the lower date and AM/PM aperture 414 will correspond with the lower designatedcity 442. Because a corresponding upper designated city is not specifically available, the watch controller can either prompt the upper date and AM/PM rings 426, 428 to a “partially displayed” position (e.g., a date and/or AM/PM designation is only partially visible through the upper date and AM/PM aperture 410) or to a blank position in which no information is displayed at the upper date and AM/PM aperture 410. In other embodiments, thewatch 400 can be configured to show or display indicia indicative of all thirty-seven time zones as described elsewhere in the present disclosure. In yet other embodiments, the year rings 422 can be omitted. -
FIG. 18A is a front view of another embodiment watch 500 in accordance with principles of the present disclosure and that can be akin to thewatch 20′ shown inFIG. 1B .FIG. 18B is a rear view of thewatch 500, andFIG. 18C is a side view. Thewatch 500 can be akin to previous embodiments, and includes various display features that provide a viewer with the ability to quickly ascertain the current date and time in a city of interest, as well as the current time in other cities across the globe. Further, thewatch 500 self-corrects the displayed information for any daylight savings time event in any of the displayed locales. Optionally, thewatch 500 is configured to automatically self-correct for daylight savings time events using with only mechanical components (i.e., in some embodiments, thewatch 500 does not include a microprocessor or other electronic components). Mechanical only-based watch constructions are known to those of ordinary skill; in some embodiments, the watch 500 (as well as other watches of the present disclosure) tie into these known constructions to achieve new, fully mechanical functionality. - The mechanical automated daylight savings time automated self-correction features of the
watch 500 are premised upon the recognition that every year, each region of the world programmatically begins and ends daylight savings time at the same time of day on the same Sunday of the same month. As a result, a mechanical movement can be incorporated into thewatch 500 that counts the number of Sundays in each month, in each time zone, and at the correct Sunday at the correct time of year, triggers the one hour movement of the displayed cities within their respective daylight savings time zone. By overlaying this consistent logic across schedules of the five regions of the world that observe daylight savings time, nine distinct states of time across the world emerge.FIG. 19 is a chart illustrating the nine distinct states. - To enable functionality of the
watch 500, thewatch 500 optionally includes a mechanical accounting of: day of week, month, date, counting of Sundays, AM vs. PM, and exact time of day, across the world for the displayed cities (e.g., forty-two cities), representing each of the world's thirty-seven time zones, clustered into the five distinct world region daylight savings time schedules. - For example, Jan. 1, 2015 is a Thursday. At this time of year, cities that observe daylight savings time in North America and Europe are in Standard Time (ST). Cites that observe daylight savings time in South America, Australia and New Zealand are in Daylight Savings Time (DST). At the beginning of January (and the beginning of every month), the
watch 500 counts the number of Sundays in that month. In 2015, February 1 is a Sunday. Thewatch 500 counts February 1 as the first Sunday of the month, and continues to count each Sunday. On the third Sunday of February (i.e., Feb. 15, 2015), thewatch 500 automatically ends daylight savings time in Brazil, automatically setting the time in Rio De Janeiro, Brazil (“RIO”) one hour back from UTC −2 toUTC − 3. Fernando De Noronha, Brazil (“FEN”), also tracked by thewatch 500 in one embodiment, is unaffected as FEN does not observe daylight savings time. The next state change on thewatch 500 occurs on the second Sunday in March in the US and Canada. In 2015, that date is March 8, and at 2:00 AM thewatch 500 automatically adjusts several North American cites to mark the beginning of DST in US and Canada. For example, Adak, Alaska (“ADK”) changes from UTC −10 to UTC −9; Anchorage, Alaska (“ANC”) changes from UTC −9 to UTC −8; Los Angeles, Calif. changes from UTC −8 to UTC −7; Denver, Colo. from UTC −7 to UTC −6; Chicago, Ill. from UTC −6 to UTC −5; New York, N.Y. from UTC −5 to UTC −4; St. John's, Newfoundland, Canada, from UTC −4 toUTC − 3. This same process continues throughout the year, enabling thewatch 500 to be a 100% accurate, mechanical, fully automated world time watch. - In some embodiments, the
watch 500 incorporates analternative UTC display 502 and an alternative city selection indicator 504 located around the outside of the watch case and bezel as shown inFIG. 18C .FIG. 18B illustrates a further optional feature of thewatch 500 in which the back cover provides a full listing of all displayed cites and their corresponding abbreviation that can be used as a guide in deciphering all of the acronyms. -
FIG. 20 illustrates one technique for setting a current time with some embodiments of thewatch 500. First, a bezel 510 (optionally another component) of thewatch 500 is rotated to bring the current or selected city to the six o'clock position (“LON” inFIG. 20 ) or other position as highlighted by the city selection indicator 504 (FIG. 18C ) where provided.Crowns watch 500. Finally,crown 516 is operated by the user to “set” daylight savings time. In this regard, thewatch 500 mechanically (or electronically) “counts” backward from the now-entered current date to determine number of Sundays passed and the number of Sundays yet to come in the current month. For example, if the day/date is “Wednesday, March 23” thecrown 516 will rotate three revolutions, counting down to the most-recent Sunday (Sunday, March 20), then thecrown 516 will rotate two more revolutions, skip-counting by 7 (13, 6) determining that at this current date, three Sundays have passed in March. The movement mechanisms provided with thewatch 500 “knows” that March has thirty-one days, and thus that one more Sunday is yet to occur in current month of March. The movement mechanisms provided with thewatch 500 then adjusts to the corresponding world wide daylight savings time state (e.g.,state 3 as shown inFIG. 19 ). -
FIGS. 21A-21I illustrate automatic transitioning of thewatch 500 upon occurrence of various daylight savings time events throughout the year.FIG. 21A provides an arbitrary starting point, showing a display of thewatch 500 on Sunday, February 7. As a point of reference, the first Sunday of November through the third Sunday in February, the United States and Canada are at standard time, while many cities in the southern hemisphere observe daylight savings time. -
FIG. 21B illustrates a display of thewatch 500 at a later point in time, and in particular Sunday, February 21. As a point of reference, the end of February brings standard time back to various locales, such as Brazil; daylight savings time continues on in Australia and New Zealand. A comparison ofFIG. 21B withFIG. 21A reveals the automated changes effectuated by thewatch 500 in the displayed time of day and UTC offset for certain cities. -
FIG. 21C illustrates a display of thewatch 500 at a later point in time, and in particular Sunday, March 20. As a point of reference, at the second Sunday in March, most cities in the United States and Canada invoke daylight savings time.

FIG. 21D illustrates a display of thewatch 500 at a later point in time, and in particular Sunday, March 27. As a point of reference, most cities in Europe invoke daylight savings time on the last Sunday in March. A comparison ofFIG. 21D withFIG. 21C reveals the automated changes effectuated by thewatch 500 in the displayed time of day and UTC offset for certain cities. -
FIG. 21E illustrates a display of thewatch 500 at a later point in time, and in particular Sunday, April 3. As a point of reference, most cities in Australia and New Zealand return to standard time on the first Sunday in April. A comparison ofFIG. 21E withFIG. 21D reveals the automated changes effectuated by thewatch 500 in the displayed time of day and UTC offset for certain cities. -
FIG. 21F illustrates a display of thewatch 500 at a later point in time, and in particular Sunday, September 25. As a point of reference, daylight savings time begins in New Zealand on the last Sunday in September. A comparison ofFIG. 21F withFIG. 21E reveals the automated changes effectuated by thewatch 500 in the displayed time of day and UTC offset for certain cities. -
FIG. 21G illustrates a display of thewatch 500 at a later point in time, and in particular Sunday, October 2. As a point of reference, daylight savings time begins in Australia on the first Sunday in October. A comparison ofFIG. 21G with FIG. 21F reveals the automated changes effectuated by thewatch 500 in the displayed time of day and UTC offset for certain cities. -
FIG. 21H illustrates a display of thewatch 500 at a later point in time, and in particular Sunday, October 16. As a point of reference, daylight savings time begins in Brazil on the third Sunday in October. A comparison ofFIG. 21H withFIG. 21G reveals the automated changes effectuated by thewatch 500 in the displayed time of day and UTC offset for certain cities. -
FIG. 21I illustrates a display of thewatch 500 at a later point in time, and in particular Sunday, October 30. As a point of reference, daylight savings ends in most cities in Europe on the last Sunday in October. A comparison ofFIG. 21I withFIG. 21H reveals the automated changes effectuated by thewatch 500 in the displayed time of day and UTC offset for certain cities. - Non-limiting examples of a
first display ring 550, asecond display ring 552, and first-fifth partial city rings 554 a-554 e useful with the watch 500 (or with thewatch 20′ (FIG. 1B ) are provided inFIG. 22 . As a point of reference, thesecond display ring 552 includes hour indicia 556 akin to previous embodiments. With the exemplary configuration ofFIG. 22 , the hour indicia 556 includes differentiators between midnight and noon (e.g., “MDNT” hour indicia 556 a and “NOON” hour indicia 556 b) as described above, as well as differentiators between morning and evening (e.g., “AM”hour indicia 556 c and “PM”hour indicia 556 d). The morning and evening differentiators can assume other formats (e.g., “DUSK” and “DAWN”), and can be incorporated into any other embodiment of the present disclosure. - Another embodiment of a
world watch 600 in accordance with principles of the present disclosure is shown inFIGS. 23A-23C . As a point of reference,FIG. 23A is a front view of thewatch 600 andFIG. 23B is a rear view.FIG. 23C is a front view of thewatch 600 with various front face display components removed, along with a representation of indicia display along a side of thewatch 600. Thewatch 600 is akin to other embodiments of the present disclosure, and generally includes a controller apparatus (not shown) configured (e.g., programmed) to automatically effectuate changes in information displayed at a face of thewatch 600 in response to various events (e.g., a daylight savings time event, user-prompted change in set time, date or selected time zone city). - The
watch 600 includes aprimary display 602, adisplay ring 604 and abezel 606. As with previous embodiments, thedisplay ring 604 displayscity indicia 608 and defines city apertures 610 a-610 e through which information provided on partial city rings 612 a-612 e can be viewed. - As best shown in
FIG. 23B , aback face 620 of thewatch 600 forms aselection aperture 622. With additional reference toFIG. 23C , information provided by interior rings 624 (collectively referenced) is visible through the selection aperture 622 (e.g., AM/PM and date information). As a point of reference, because the view ofFIG. 23C is taken from a front side of thewatch 600 andFIG. 23B is from the back side, the information on the interior rings 624 is “reversed” inFIG. 22C (and would not otherwise be visible in the view ofFIG. 23C as the information is “behind” or on the “back side” of the interior rings 624). Finally,city selection indicia 626 can be displayed on theback face 620 in close proximity to theselection aperture 622, readily informing the user as to the particular city or locale to which thewatch 600 is to be set (e.g., “CHICAGO”). - With the above construction, a user “sets” the
watch 600 to the designated city (i.e., the city selection indicia 626) by rotating the bezel 606 (or other component such as a designated crown) to display the current AM/PM and date information in theselection aperture 622 for the designatedcity 626. The current time is shown at the front display as with previous embodiments. - Although the present disclosure has been described with reference to preferred embodiments, workers skilled in the art will recognize that changes can be made in form and detail without departing from the spirit and scope of the present disclosure.
